Our first view of the dunes at Great Sand Dunes National Park. The waves in Medado Creek created by the strong winds seemed to travel up stream as we crossed toward the dunes. If you looked straight down when walking, it seemed as if you were standing still due to an optical illusion. #sand #dunes #greatsanddunes #bluesky #creek #water #desert #beautiful #hiking #hike #adventure #nature #outdoors #roadtrip #fypyes #findyourpark #rei1440project
